4Claims.

This invention relates to apparatus for and process of operating on sheet metal stock, wherein it is fed to and between a pair or pairs of cutters to cut or slit the stock into longitudinal 5 strips or sections, the edges ofthe strips or sections conditioned, trimmed or finished ready for subsequent treatment, and then, by preference,

the strips or sections wound into a coil or coils, whereby they may be handled or transported. 10 The apparatus is adapted for operating on sheet metal stock that is hot or cold rolled and of varying width. thickness and length.

One object of the invention is to provide an improved apparatus of .this character that is is relatively simple in construction and has large capacity. 7 Another object of the invention is to provide an apparatus of the type shown in the co-pending application filed April 15, 1935, by Carl M. 20 Yoder, one of the petitioners herein, Serial No. 16,373,.Patent2,179,461, November "I, 1939, but embodying improvements therein whereby the apparatus is materially simplifiedand reduced in size and cost of manufacture and large ca- Another object of the invention is to provide an improved machine for edging or conditioning relatively narrow metallic strips.

A further object of the invention is to provide '36 an improved process of edging or conditioning metallic strips of varying predetermined widths in rapid manner.

Other objects of the invention will be apparentto those skilled in the art to which our invention relates from the following description taken in connection with the accompanying drawings. wherein Fig. 1 is a plan view of 'an apparatus embody ing our invention.

In the drawings, iindicates as an entirety a mechanism and the driving means therefor for trimming the opposite edges of the sheet metal stock A and cutting or slitting it into longitudinal strips or sections a; 2 indicates as an entirety a set of stock feed rolls and the driving means therefor; 3 indicates as an entirety a mechanism for guiding and edging, conditioning or ups-setting the opposite edges of the strips or sections; 4 indicates as an entirety a mechanism for rolling down the conditioned or up-set edges of the strips; and 5 indicates as an entirety a mechanism for coiling the strips and the driving means for such mechanism.

Of the trimming and slitting mechanism I, 6 indicates a supp rt having standards I in which are mounted upper and lower shafts. The shafts in turn carry pairs or sets of cutters I, the outermost pairs serving to trim the opposite edges of the material and the intermediate pairs or sets 5 of cutters serving to cut the stock into strips or sections'each of any predetermined width dependent upon the spacing of the adjoining pairs or sets of cutters i. As shown in Figs. 1 and 2, 1 the stock A is disposed horizontally and de- 40 livered from a coil (not shown) such for example, as illustrated in the aforesaid application Serial No. 16,373. The mechanism I preferably includes feed rolls 8,9, arranged forwardly and rearwardly of the pairs of cutters 'I'. The shafts for the cutters I and feed rolls 8,1, are driven through suitable'gearing in a casing ill, and speed reducing means II from a motor 12. The parts above referred to are preferably substantially similar to that shown in the aforesaid ap- 60 plication to which reference may bemade for further illustration and disclosure thereof; it being understood that in the present applicationno claim is made to the form of trimming and slitting mechanism and that any desired constructionof such mechanism may be used. The material trimmed of! by the outer pairs or sets of cutters is preferably guided downwardly as shown at a to a scrap-cutting mechanism (not shown) which may also be of the construction shown in said application.

The feed mechanism 2 and the rolling down mechanism 4 are preferably substantially equally spaced forwardly and rearwardly of the guiding. and conditioning mechanism 3 for the reason that in passing through the latter mechanism, the strips a are flexed or turned from a common horizontal plane, in which they pass through the feed mechanism 2, to vertical positions in side by side substantially parallel relation and then flexed or turned back to a common horizontal plane by the mechanism 4 for guiding and feeding to the coiling mechanism 5. This arrangement permits the strips a to be flexed or turned to their vertical positions for engagement with the guiding devices and edging, condition.- ing or up-setting rolls and flexed or turned back to normal positionwithout affecting thefeeding of the strips ortheir relation to each other in passing through the mechanism 2 and mechanism 4.

The mechanism 2 is mounted on a frame I3, which by preference also supports the mechanisms 3 and 4. The mechanism 2/ comprises the following: l4 indicates standards formed with seats for bearing boxes II in which are suitably mounted upper and lower shafts I. At one side the shafts II are driven through suitable speed reduction gearing within a casing H, by a motor ll. Either or both of the standards l4 may .be mounted on the frame "for adjustment transversely thereof. The bearing boxes for the-upper shaft |9 may be raised and lowered by suitable means, operated by a hand wheel l9, to vary the space between the shafts :43 according to the thickness of the strips (1. "Bhe mechanism 2 and the driving means therefor may be of any desired construction and therefore it is not thought necessary to further illustrate and describe in detail its parts. I

The combined guiding and edging, conditioning or up-setting mechanism 3 consists of the 'means for engaging the opposite edges of the strips a to condition or up-set them and means arranged forwardly and rearwardly of said means .for guidingthe strips into vertical side by side 1 I relation thereto and therefrom; that is, the guide means at the front and rear of the conditioning means co-operate to guide each strip into and maintain it in a vertical plane while being engaged by the adjacent pairs of edging or conditioning elements 23.

The edging, conditioning or up-setting means consist of pairs of annular elements 23', one pair for each strip, each element being formed with a groove 2| to receive the adjacent edge of a strip, the cross sectional shape of the groove corresponding to the shape, in cross section, desired to be imparted toor eifected upon the edge of the adjacent strip a, examples of such shapes being shown in Figs. 16, 1'1, 17a and 17b. As will be readily understood,-the cross sectional shape of the longitudinal edges of each strip may be varied at will, dependent upon the ultimate use -ortreatment of the strip. The opposite edges of: each strip may be similarly or differently shaped and by preference both edges of each strip are acted on simultaneously. but the invention is not to be limited to such simultaneous operation. The conditioning mea s the guiding means are so mounted that relative transverse adjustment thereof may be effected, the latter means being in the present disclosure adjustable relative to the conditioning elements 20. As shown in Figs. 4, 5, 8 and 9 the elements .20 a re removably mounted on upper and lower are uniformly spaced and the edges on all of the strips similarly edged. In this arrangement we may provide on the edges of the strips any one of the cross sectional shapes formed by the pairs of related grooves 2|, .b'y adjustment of the guide means without adjustment or disassembly of the elements or the mounting therefor. However, the invention is not to be so limited since, by substitution of different edging elements, one or more strips a. may be edged or conditioned differently from the remaining strips.

Referring to Figs. 1, 2, 3 and 4, 24, 25,,indicate standards mounted on the support I3, one thereof (standard being movable laterally to an inoperative position (see dotted lines in Fig. 3),

whereby the shafts 22, 23, may be assembled or disassembled and the edging elements may be removed and others assembled on the shafts. When in operative position, the standards 24, 25,

are secured to'the support l3 by bolts 26, the

support being formed with slots 21 to permit movement of the bolts, which secure'the standard 25 in position, when the latter is moved laterally and a slot 28 for 9. lug 29 which depends from the latter standard (see Fig. 3). The lug 29 is threaded to receive a feed screw 30, which is rotated by a wheel 3|. The outer end'portion of the screw 30 is mounted in a suitable bearing 32 and provided at opposite sides thereof with the shaft 22 may be raised and lowered, at will, 50

to permit the strips a to be inserted between the pairs of edging elements 20 when the apparatus is to be set in operation. The lower end of each rod 33 is provided with a head 31 fitting into a recess formed in a block 33 which is suitably secured to theadiacent bearing box 35. The rod 36. slides endwise in and extends through a tubular member 39 adjustably mounted in a bridge 40 seated on the upper end of the adjacent standard. The -tubular member 39 is preferably formed integrally with a casing 39a on which is mounted a cylinder 4| enclosing a piston 4|a. Between each piston rod and upper end ot the adjacent rod 36 is provided a toggle 42, so that when the piston 4|a is in one position=it acts through the toggle 42 to move the adjacent rod downwardly and when the piston 4|a is moved to its other position the adjacent rod 36 is moved upwardly. The pistons 4|a are operated by a suitable fluid under pressure supplied to the outer or inner sides of the pistons by pipes 43.

The supply of the fluid through the pipes 42 is controlled by a suitable valve (not shown) to control the movement of the pistons in the proper direction simultaneously .(toward or away from each other in the present disclosure-r-see Fig. 3), whereby the shaft 22 is bodily raised or lowered. The tubular members 25 are adjustably mounted in the bridges 40, so that when the shaft 22 is moved downwardly to its final POSi-r tion by the action of the toggles 42, the edging elements 25 will operatively engage the strips-according to the predetermined width thereof. This adjustment of the members 55 is effected by providing screw threads on their outer walls and the walls of the openings through the bridges 4,5, the members being locked in adjusted position by upper and lower nuts 44 which are tightened on the members 25 against theopposite faces of the bridges. Provision is therefore made for adjusting or spacing the elements 25 according to varying widths of the strips a.

The elements 25 are mounted on each shaft 22, 25, in side by side relation betweena fixed collar 22' adjacent one end of the shaft and a nut 22a threaded on a portion of the shaft near its other end, a spacer '45 being preferably pro? vided between the nut 22a and the adjacent element 2|l. when found desirable, spacers may be provided between adjoining elements 25. The shafts 22, 23, extend through the bearing boxes 25, which are mounted in the standard 24, and

carry on their outer ends worm gears which mesh with worms 4! fixed to a driven shaft 45. At its lower end the shaft 45 is provided with a bevel gear 45 in mesh with a bevel gear 55, which is fixed to a shaft-5|, the latter in turn being connected to and driven by the shaft of the motor l5.

The strip guiding elements forwardly of the strip-edging means and the strip guiding elements rearwardly thereof, are similar in con-. struction and therefore reference will be made to one such means, although corresponding parts are indicated by the same reference characters to insure a clear understanding of the construction, reference being made particularly to Figs. 4, 5, 6 and 7. ,52 indicates a supplemental support which in this-form of construction consists of a bar rigidly (but detachably) secured at its opposite ends to the opposed faces of the standards 24, 25, the detachment permitting the bar to be disconnected from the standard 25, when the latter is moved laterally, as shown in dotted lines in Fig. 3. The bar 52 is formed with front and rear slots 53 extending transversely to the feed of the strips a and each adjustably supports b tween its side walls a pair of guide devices 54 for one of the strips a, each guide device being adiustable independently of the other device of a pair and movable from end to end of the adjacent slot 52, whereby each pair of devices may be related to guide strips of different thicknesses and also related to any pair of edging grooves 2| formed in the edging elements 25. Each device 54 comprises the following: indicates a shaft extending through the ad'iacent slot 53, the sides of the shaft throughout, the height of the bar 52 being flattened (see Fig. 'l) to slidably and non-rotatively engage the walls of the slot 53,

whereby the shaft is held'against turning. The upper end of the shaft v55 is provided with a bushing" having a flangeat itslower end to engage the bar 52. A nut 51 threadedton the upper end of the shaft 55 and tightened through a washer 51a against the bushing in opposition the rolls 54.

to the head 55a on the lower end of the shaft 55 serves to adjustably secure the shaft to the bar 52;- 58 indicates a roller mounted to rotate onthe bushing 55. By preference, theroller 55 is promits the over-all width of the machineto be reduced to a minimum and simplified.

As shown in Figs. 1 to 6, inclusive, the pairs of guide devices 54 forwardly of the edging elements turn or twist the strips 41 from the horizontal position as they pass the feed rolls l5, l5, to the vertical position and co-operate with the pairs'of guide devices 54 rearwardly of the edging ele- .ments to guide and maintain the strips in spaced side by side or vertical positions for feeding to and between the edging elements; whereas the rolls of the mechanism 4, in the preferred form of construction, turn or twist the strips 11 in the reverse direction to a horizontal position, for feeding to the coiling mechanism 5 and to permit treatment of the strip edges when desired, as

hereinafter set forth.

The mechanism 4 may be-similar in construction to the mechanism 2 where further treatmen of the strip edges is not necessary.

If desired, the strips 1 may be delivered direct from the edging mechanism to suitable coiling drums, but by preference they are returned to the horizontal position and in a common plane so as to be coiled simultaneously on a single drum.

In the present disclosure tlie mechanism 4 is constructed to effect feeding of the strips trend is also constructed toeffect further treatment thereof, namely, to roll down the up-set edges of the strips, as shown in Figs. 14, 15 and 16. Referring to these views, 59, 59, indicate standards mounted on the support l3 and formed with' openings 55 to receive and support pairs of bearing. boxes 5|, 52, the boxes 5| serving to support a pair of roll-down rolls 53 and the boxes 52 serving to support a pair of back-up rolls 54. The boxes 5| are permitted to float in the openings 34 so that the rolls 53 are free to be acted..upon by The boxes for the lower'roll 54 rest on the bottoms of the openings 55' so that this roll is stationarily supported, whereas the upper f 55 and provided with heads 51 fltting' recesses in blocks .58 suitably secured to'the adjacent boxes 52. In this arrangement, the rolls 54 are spaced so that the strips a may pass between the rolls 52 and the latter, by reason of the engagement of the rolls 54 therewith will roll down the upset edges of the strips to the planes of their opposite faces, as shown in lfig. 15. As the rolls 54 are power driven, the friction between them and the rolls 53 will serve to rotate the latter. The driving means for rolls 54 consist in extending their supporting shafts beyond onei of the standards 59 and providing on such extended ends v'orm wheels 59 which mesh with worms 55a on a shaft 15, the latter being driven through gearing in a casing 'II by the shaft 5|.

12 indicates uprights disposed forwardly and rearwardly of the-mechanism l and supporting [the inner ends of platforms I2 which extend,

- between the mechanism a and mechanisms 2 and 4, the outer ends of the platforms being secured to angles ll, mounted on the adjacent standards. The platforms 13 support the strips a when being positioned between the edging elements and the rolling .down rolls 83.

Figs. 8 to 13, inclusive, illustrate a modified form of construction wherein each guide means for all of the strips forwardly and rearwardly of the edging mechanism 3 is mounted on the support l3 so that the standard may be moved independently of the guide means and their supports, and supplemental means, indicated as an entirety at 18 are provided for guiding the strips as they pass between the pairs of edging elements 2'.

Referring to these figures, 16 indicates inverted substantially U-shaped members forwardly andrearwardly of the edging mechanism 3, the legs of each member being provided with flanges 18 which are secured to the support l3 by bolts 18".

The legs of each member I6 are connected by (a) a crossplate 18 on which are adjustably mounted pairs of guide devices 54, the latter being preferably similar in construction and similarly mounted to the guide devices already referred to, and (b) a cross support 19, the purpose of which will later appear. As shown in Figs: 8 and 9, we form in the plate 18 a third slot 53' in which are supported the shafts of auxiliar guide devices 54', one for each inner pair of guide devices 54, except the.c enter pair. Each auxiliary device 54' is similar in construction to each of the devices 54 and co-operates with the adjacent inner pair of devices 54 to prevent contact of the "stripe guided by said inner pair of devices with the adjacent outer pair of devices 54. This constructionincorporating the auxilimy guide devices 54' is advantageous where the stock A is slitted into strips a that have a width less than the distance or space between the related sets of grooves 2| and the outerstrips have to be laterally separated for alinement with the edging grooves 2|.

Of the supplemental guidemeans I5, 80, indicate pairs of brackets, one for each set of edging elements 28, adjustably mounted on each cross support 18, and each pair of brackets on one support 19 alined with the correspondingly related pair of brackets on the other support ,18.

The brackets .80, 88', are independently adjustable transversely of'the feed of the strips a on the supports 18, whereby guiding elements 8| supported by the brackets may be alined with the selected edging grooves 2land also related to accommodate -diilferent thicknesses of the stock. To provide for this adjustment, each bracket is secured to the adjacent support 19 by a bolt 82, which extends through a slot 82' formed therein, the slot being elongated as shown in Fig. 12.

One pair for each pair'of brackets Ill, 80', and

the other pair of brackets 80, 80', alined therewith, each plate of eachpair being secured at its opposite ends to one bracket of one pair and the corresponding bracket of the other pair of bracketsn As shown in Figs. 8, 10 and 12, the pairs of brackets 80,. 80', related to. each-set of edging elements support the adjacent pair of guiding plates 8| upon-opposite sides of and in close relation to one" of the strips 41 so as to guide the strip as it passesto and between the adjacent set'of edging elements 28 and to prevent bucklin 0f the strip due to the pressure of these elements Each guide plate 8| preferably comprises up- 3 per and lower sections, the lower section being bolted to the adjacent brackets and the upper section being adjustably secured thereto for adiustment with the upper shaft 22 according to the widthof the strips, this adjustment being provided for by forming vertical slots 83 in the brackets 80, 80' for the, bolts that secure the upper section thereto.

In order that the plates 8| may be related to substantially the entire surfaces of the opposite faces of the strips 0, and at the same time provide for the adjustment above referred to, the inner edges of the guide sections are provided with complementary edge portions which permit adjustment of the upper section without efshown in the co-pending application Serial No.

57,903 filed by Carl M. Yoder, one of the petitioners herein, now Letters Patent No. 2,116,057, dated May 3, 1938. In coiling the strips they may, if desired, be fed to and coiled on two or more drums.

From the foregoing description it will be noted that our invention adapts itself to theredging or conditioning of strips that are relatively narrow. The strips are fed in side by side relation, with their surfaces parallelly related, in. a common plane, so that the edging elements for all of the strips may be molmted on a pair of shafts, thereby materially slmplifyingthe construction, while providing for simultaneous treatment of all the strips.

From the foregoing description it will also be noted that sheet stock of any desired width and/or of indefinite length may be supplied to the trimming and slitting mechanism and fed forward by it or other feeding mechanism, the

strips separately turned longitudinally at an angle for engagement with the edging elements and then by preference turned into a common plane for coiling.

In the present disclosure, the stock is fed in a horizontal plane and trimmed and slitted into strips, which are then separately turned into a right angle position and edge conditioned and thereafter returned to the horizontal position. In this process and arrangement, the machine is of a simplified character, has large capacity and provision is readily made for providing variously shaped or conditioned edges on the strips.

To those skilled in the art to which our invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without detion. Our disclosures and the description herein are purely illustrative and not intended to be in any sense limiting.

What we claim is: v i 1. In apparatus of the class described, the com bination of means for supplying sheet metal stock,

mechanism for slitting the stock longitudinally into strips, a pair of driven rolls for feeding the strips in substantiallyedge to edge relation, sets of edging elements, one set for each strip, mechanism between'said pair of feed rolls and said sets of edging elements for separately turning the strips longitudinally into an, a u ar position, said turning mechanism being lustable transversely to the direction of feed of the strips and operating to guide the stripsto the respective related grooves formed in said sets of edging elements; guide meanson that side of said sets.

of edging elements remote from said turning mechanism, and a pair of driven feed rolls cooperating with said guide means for turning the strips longitudinally into substantially edge to edge relation for feeding thereby.

2. In apparatus of the classdescribed, the combination of means for supplying sheet metal stock, mechanism for slitting the stock lo ngitudi and operating to guide the strips to the respective related grooves formed in said sets of edging elements, guide means onthat side of said sets of-edging elements remote from said turning mechanism, a pair of driven feed rolls cooperating with said guide means for turningthe strips longitudinally into substantially edge to edge relation for feeding thereby, and means-for coiling the strips. a

3. The herein disclosed process which consists in continuously feeding sheet metal and longitudinally slitting the sheet metal into strips, simultaneously turning the strips about substantially longitudinal axes into an angular position, then conditioning the opposite side edges of the strips, then turning. the strips about substantially longitudinal axes into a common plane and feeding them to a supporting means.

4. The herein disclosed process which consists in continuously feeding sheet metal and longitudinally slitting the sheet metal into strips, si-

' longitudinal axes into a common plane and feedingthem longitudinally, and then coiling the strips.
